Abstract
Cyclotron resonance and magnetophonon resonance studies have been made of superlattices grown from thin layers of Ga. //4//7In. //5//3As and InP, which exhibit two dimensional behavior at temperatures up to 250K. The electron effective mass varies with layer thickness in reasonable agreement with the calculated non-parabolicity. The LO phonon energies are calculated from magnetophonon oscillations and mass values obtained from cyclotron resonance. A strong series of oscillations results from the dominant 'GaAs-like' mn mode in GaInAs. A second, weaker series corresponds to the energy of the InP LO phonon. This is evidence for a long range phonon interaction, with the field of the phonons extending into the GaInAs to cause a significant coupling with the electrons bound in the quantum wells.
